Joshua L. ★★★★★

Needed a reliable seal for my home water filter system, and these o-rings fit perfectly—the 70 durometer is firm enough without being too stiff. Glad they're FDA compliant for peace of mind with drinking water.

Julian ★★★★★

The 70 durometer hardness is exactly right for the water filter housing I repaired—these seals fit snugly without being too stiff. The pack of 125 will last me years, so the value is incredible for genuine FDA-compliant rings.

Samuel ★★★★★

I needed replacements for a specific dash number and these 1.6" ID rings fit perfectly. The 70 durometer feels just right for my application, and the 125-count pack gives me plenty of spares.
